PROBLEM TO BE SOLVED: To provide a concrete foundation structure having a first part supported on a ground and a second part spanned between the first parts, along with a construction method thereof, capable of mitigating impacts on residents in a neighborhood by preventing direct conveyance of vibration from the second part to the ground.SOLUTION: When casting concrete in a space for forming a second part 15, a timbering 20 installed between the second part and a ground 1 is formed of a material that may be removed by dissolution or biodegradation. After the concrete cast in the space for forming the second part 15 develops strength, the timbering 20 is dissolved or biodegraded, to bring the second part 15 in a non-contacting state floating above the ground 1.SELECTED DRAWING: Figure 3 |
